The value of x is 2 is and y is -1 is after solving equation by elimination method

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.

To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

5x + 7y=3 .....(i)

-5x + 7y=-17......(ii)

Solve equation ii and iii

-5x + 7y=-17

5x + 7y=3

14y = -14

y = -1

put the value of y in equation 1

5x + 7y=3

5x + 7(-1)=3

5x - 7 = 3

5x = 10

x =2

Answer: if you are talking about mixed number form the answer is 1 1/11 the improper/exact form would just be twelve over eleven (12/11)

Step-by-step explanation:

The graph of the line with the slope of 4/3 and goes through the point (1,3) has been plotted

The slope of the line = 4/3

The line is passing through the point = (1,3)

Here we have to use the point slope form the line

The point slope form of the line = [tex](y-y_{1} )= m(x-x_{1})[/tex]

Where m is the slope of the line

[tex](x_{1},y_{1} )[/tex] is the coordinate of the point

Substitute the values in the equation

(y-3) = 4/3 (x-1)

y-3 = (4/3)x - 4/3

y = (4/3)x - 4/3 + 3

y = (4/3)x + 5/3

We got the slope intercept of the line.

Plot the graph using the slope intercept form of  the line

Hence, the graph of the line with the slope of 4/3 and goes through the point (1,3) has been plotted

1)the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag is $16.2

2) The cost per head per month is $23.4

3) The cost per head per month is $39

What is Equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.

1) The grains use feed for one horse = 4.5pound

The cost of 1 bag of grain = $27 per 50lb

The cost of 1lb grain = $0.54

Now the monthly cost of the grain will be:

Cost/head/day x # of days in month = Cost/head/month

$0.54 x 30 = $16.2

Hence, the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag is $16.2

2) The amount of grain use to feed for one head = 1.5pound

If the grain is feed twice a day = 1.5 x 2

                                                   = 3.0

The cost of the grain = $13 per 50lb

The cost of 1lb grain = 13 / 50

                                  = $0.26

The cost of grain feed in one day = 0.26 x 3

                                                        = $0.78

The cost of per head per month =

0.78 x 30 = $23.4

Hence, The cost per head per month is $23.4

3)The amount of grain use to feed for one head = 2.5pound

If the grain is feed twice a day = 2.5 x 2

                                                   = 5pounds

The cost of the grain = $13 per 50lb

The cost of 1lb grain = 13 / 50

                                  = $0.26

The cost of grain feed in one day = 0.26 x 5

                                                        = $1.3

The cost of per head per month =

1.3 x 30 = $39

Hence, The cost per head per month is $39

The value of n for a line that passes through point A(n, 4) and point B(6, 8) and is parallel to  y = 2x - 5 is 6.

No matter how far we extend a parallel line, it will always remain straight. Take a look at the parallel lines in the following illustration. Lines "p" and "q" are parallel to each other as are lines "a" and "b."

We know that parallel lines have same slope, so the slope of y = 2x - 5 is 2 according the y intercept form, y = mx + b

Now using the point-slope form we will find the line parallel to Point B (6, 8)

y − y₁ = m(x − x₁)

Put m as 2, y₁ as 8 and x₁ as 6, and we wil get

y − 8 = 2(x −6)

y = 2x − 4 or

2 = (y + 4)/x           (slope)

We will us point-slope form for point A(n, 4) too

y − 4 = 2(x −n)

y = 2x − 2n + 8 or

2 = (y - 8 + 2n)/x

As slope 2 is same in both points it means their equations are same too

(y + 4)/x  =  (y - 8 + 2n)/x

Lest solve for n

(y + 4)/x  =  (y - 8 + 2n)/x

y + 4 =  y - 8 + 2n

4 = - 8 + 2n

4 + 8 = 2n

2n = 12

n = 12/2

n = 6

Thus, the value of n for a line that passes through point A(n, 4) and point B(6, 8) and is parallel to  y = 2x - 5 is 6.

Step-by-step explanation:

D has a value of 13 using vertical angles.

What is a vertical angle?

Assuming that C and D constitute vertical angles

The formula is C = (-3x) + 58 and D = x - 2.

We must ascertain what D's measurement is.

Vertical angles are really a pair of opposing angles created when two lines cross.

A and B in the figure represent vertical angles. C and D are also.

Angles vertically are always congruent. Accordingly, in this illustration, A, B, and C, D

Therefore, value of C = D (-3x)+ 58 = x – 2

By assembling,

(-3x )- x = (-2) - 58

By doing more math, 4x = 60 (-4x = - 60)

4 x = 60/4 x = 15 when both sides are divided.

So, ∠D = (x - 2) and  

= 15 - 2 

So, ∠D = (x - 2) and

It is to be noted that the distance between P and ρ is: [tex]\approx[/tex] 15.52

This solution is arrived at using the Line Segment theorem. See further explanation below.

The length of the line segment connecting two points in a plane is defined as the distance between two points. The method for calculating the distance between two locations is often written as

[tex]d = \sqrt{((x_{2} – x_{1})² + (y_{2} – y_{1})²).} [/tex]

Hence, since we have ρ is to contain two points, we will solve as follows:

Distance between ρ and P where ρ is (0, -3) and (7,4)

we have to multiply the coordinates.

To multiply coordinates, you have to multiply the corresponding values.

That is

[tex]x_{1} \times x_{1} [/tex]

and

[tex]y_{1} \times y_{1}[/tex]

In this case:

x1 = 0

[tex]x_{1} = 0[/tex]

also

[tex]x_{1} = 7[/tex]

[tex]y_{1} = - 3[/tex]

also

[tex]y_{1} = 4[/tex]

Hence, for

[tex]x_{1} = 0 \times 7 = 0[/tex]

for

[tex]y_{1} = - 3 \times 4 = 12[/tex]

Hence, solving for the distance between P and ρ, we'd use coordinates of P as = (4, 3); and coordinates of ρ as = (0, -12)

Recall that distance is given as

[tex]d = \sqrt{((x_{2} – x_{1})² + (y_{2} – y_{1})²).} [/tex]

Hence,

d = √((0-4)² + (-12-3))²)

[tex]d = \sqrt{{(( {0 - 4}^{2} }) + { (- 12 - 3)}^{2} } [/tex]

Expand the brackets

[tex]d = \sqrt{ { - 4}^{2} + ( { - 15}^{2} } )[/tex]

[tex]d = \sqrt{16 + 225} [/tex]

[tex]d = \sqrt{441} [/tex]

Answer:

x = 70

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

x + 160 + 110 + 105 + 95 = 540

x + 470 = 540 ( subtract 470 from both sides )

x = 70

The speed of the particle at time t=4 is 5 units.

We are given the x(t) vs time curve.

To find:

Speed of particle at t = 4

We know that the slope of x-t curve represents the speed of the particle.

To calculate the speed of the particle at t = 4, We will calculate the slope of the curve at t = 4

Slope = y₂ -y₁ / x₂ - x₁

Slope = 40 - 10 / 6 - 0

Slope = 30 /6

Slope = 5

From here we can say that the slope of the curve between x = 0 and x = 6 is equal to 5.

So the value of speed is also 5 units.

We are given a system of linear equations in two variables. The first equation is y = (-1/2)x-1. The second equation is (-1/4)x+y+4 = 0.

We need to find the solution of the system of equations. We will use the substitution method to solve for the values of "x" and "y".

y = (-1/2)x - 1

(-1/4)x + y + 4 = 0

Substitute the value of "y" from the first equation into the second equation.

(-1/4)x + (-1/2)x - 1 + 4 = 0

(-3/4)x+3 = 0

(3/4)x = 3

x = 4
